Description
Technical field
The present invention relates to a kind of mobile device, particularly about the operating means and the method for a kind of mobile device financial products quotation screen display line chart.
Background technology
Adopting vertical picture to show mostly by present mobile device (claims the portrait picture to show again, portrait screen display) can't switch to horizontal picture demonstration (claims the landscape picture to show, landscape screen display) reason is that operating system (operating system) and the hardware because of mobile device is not supported horizontal demonstration.Yet laterally picture shows the displaying ratio near personal computer (PC), especially more can show the advantage that horizontal picture shows at browsing page or when seeing picture.So partly operating system adds this horizontal menu display function successively, and allow the user to switch vertically/laterally picture demonstration, for example Microsoft Windows Mobile 5.0 (not comprising SmartPhone Edition), Microsoft Windows Mobile 6.0, minority Symbian version, the iPhone of Apple computer, Android of Google or the like, how remaining operating system closed or open mobile device does not provide horizontal picture to show.
Operating system at mobile device provides under the situation of horizontal menu display function, the mobile device hardware vendor is designed/direction sensor (directional sensor), balance sensor (the balance sensor that make, force transducer gravity sensor weighs again), the entity switching key ... etc., can cooperate running.For example, after the user rotated to certain angle with iPhone, screen-picture just can be from vertically forwarding to laterally; Or when the user will laterally go to vertical type, screen also will transfer functions such as vertical demonstration automatically to.The software application of mobile device (software application), for example financial tape reading software is identical with the sensor, and also needing has under the situation of supporting horizontal picture demonstration in the operating system of mobile device, can cooperate running.And so-called " operating system do not support horizontal picture show ", in fact the most important promptly this operating system do not provide horizontal literal to show, meaning be literal can't inverse clock or clockwise revolve and be shown on the screen after turning 90 degrees.
Please refer to Fig. 1, it is that the Java financial tape reading software vertically shows the synoptic diagram of " the real-time line chart of weighted index " on mobile device, it has illustrated and has been used at present on the mobile device 10 (mobile device), for example: mobile phone, PDA, stock handset or screen are all vertical picture demonstration (portrait screen display) less than the screen-picture 14 of Java financial tape reading software 12 demonstrations of 7 cun mobile Internet access device (Mobile Internet Device/Ultra-Mobile PC).Wherein, the financial tape reading software 12 real-time line chart information that is shown in screen-picture 14 has: financial tape reading software function 1, financial tape reading software function 2 18, command line 28.And the below of mobile device 10 mainly contains: mobile device options button 1, mobile device options button 2 22, directionkeys 24 are controlled for the user with mobile device keyboard 26 several buttons.
" line chart in real time " with Fig. 1 is example, wherein, the transverse axis of line chart (x axle) the representative time, the longitudinal axis (y axle) representative " valency/amount of weighted index ", the column diagram (bar chart) of line chart below is represented trading volume, the broken line graph of line chart central authorities (broken line chart) representative " variation of each time point of weighted index ", free in addition above line chart, price, ups and downs dot information are for user's reference.Vertical picture shows that the advantage person of being to use of line chart can discover the data variation on the longitudinal axis (y axle), and this is that mobile device 10 screen heights (vertically) are long event than width (laterally).On the contrary, show that vertically line chart is limited for fear of screen width, the transverse axis spacing suffers compression to be difficult for allowing the user discover data variation on the transverse axis (x axle) unavoidably, and this is the disadvantage of prior art.
Prior art then can be known inquiry valency/amount sometime if time shaft (X-axis) spacing is amplified.Yet as if amplification time distance between axles, the user certainly will need so that a left side/24 operations of right key are with the scrolling screen-picture in vertical picture shows, it is inconvenient to belong in fact.
In addition, the technical Analysis figure in the financial tape reading software (in diagram in do not describe) again with the above-mentioned same day real-time line chart different.The same day, real-time line chart was because of punctum (tick) fixed amount, but if the x axle is widened then punctum figure lateral widening, made things convenient for the user to inquire about sometime valency/amount; Technical Analysis figure widens then and can paint in figure into more punctum as if the x axle, if Day Line Chart then can be inquired about the data of more transaction fates in the x axle of widening.
In sum, vertical picture of prior art mobile device financial tape reading software shows that line chart can't satisfy the many-sided demand of user.For example, when checking real-time line chart, need amplification valency/amount axle (being that vertical picture shows) sometimes, need amplification time axle (being that horizontal picture shows) sometimes; When checking technical Analysis figure, more need horizontal picture to show to check more multidata.
Therefore, be necessary to propose a kind of mobile device that allows in fact and carry out the software that horizontal picture shows line chart, allow and no matter whether support the mobile device of horizontal display operation system to install and to use, can satisfy the potential demand that the user operates various financial tape reading softwares.

Embodiment
The present invention can be used in originally operating system and hardware all not support on the mobile device 10 of horizontal menu display function, for example: mobile phone, PDA, stock handset or screen are less than the Java application software of 7 cun mobile Internet access device (Mobile Internet Device/Ultra-Mobile PC) etc.Below, will lift the Java financial tape reading software is example.
Technical matters about " operating system can't support horizontal literal to show ", the present invention is laterally reducing display text information in the picture as far as possible, and required Word message transfers graphic presentation (comprising each spoken and written languages, numeral, symbol ... the literal that waits need can laterally be shown by the operating system support) without exception to.And literal transfers graphical format to is to reach in following four kinds of modes:
1. moving three dimension (3D) application programming interfaces (Mobile 3D API) of utilization Java are set up a 3D Drawing Object (graphics object), in addition literal is stored on a two dimension (2D) Drawing Object, and with this 2D Drawing Object in conjunction with (bind) to the 3D Drawing Object, with Java Mobile 3D API function this is revolved in conjunction with Drawing Object clockwise or inverse clock again and turn 90 degrees, can show horizontal literal.
2. use SVG suite of tools (the Scalable Vector Graphics Kit for Java2 Micro Edition of Java2 mobile edition, SVG Kit for J2ME) produces the literal of SVG vector graphics format with program, and with Java Mobile 2D API function its clockwise or inverse clock are revolved to turn 90 degrees, can show horizontal literal.
3. with the map file edit routine literal is revolved and be saved as figure shelves form after turning 90 degrees, with the literal loading procedure of map file form, can show horizontal literal again.As for scheming the shelves form including but not limited to BMP, JPEG/JPG, TIF/TIFF, PNG, GIF, SVG etc.
4. for the mobile device of not supporting Java Mobile 2D API and Java Mobile 3D API, then utilization has the double buffering display memory (Double Buffering) and trigonometric function rotation calculation (Rotation Algorithm) method of two memory buffer, can be in real time and dynamically show vertical literal character code to second display memory that is positioned at background (Secondary Buffer) and produce the literal bit image, repeat that then this bit image is rotated 90 degree through trigonometric function rotation algorithm (Rotation Algorithm) original place and become horizontal character image, at last will this horizontal bit image copy to the screen display internal memory (Primary Buffer) of the prospect of being positioned at, just can reach real-time and dynamic Word message and turn to.The present invention uses trigonometric function rotation algorithm as follows:
(x ', y ')=(x*cos (A)+y*sin (A)-x*sin (A)+y*cos (A)), wherein:
The vertical image level coordinate of X=; The vertical image vertical coordinate of Y=; X '=landscape images horizontal coordinate; Y '=landscape images vertical coordinate; The A=anglec of rotation.
The present invention adopts this dynamic Word message Rotation Design, more can generally be performed in all mobile phone, PDA, stock handset or screens of supporting Java less than 7 cun mobile Internet access device (Mobile Internet Device/Ultra-Mobile PC).
Above-mentioned way can be avoided the aforementioned operation system not support horizontal display text and cause the mobile device can't be with the shortcoming of horizontal demonstration, and laterally show line chart focus on allow line chart amplify and easier checking, when reducing the relevant information that literal shows, unnecessary layout space can allow line chart divert, to amplify line chart.And the literal of hiding demonstration relevant information comprises but is not limited to: software titles row (application header), page title row (page header), command line, software function key, financial products title, transverse axis and longitudinal axis unit indicate (legend), and meaning is that line chart laterally shows in the amplification mode.
When the user identical with the prior art mode of operation during with vertical picture display operation software, as shown in Figure 1.When the user checks vertical line chart in screen-picture 14, promptly can the financial tape reading software function one 16 launch menus and show (as shown in Figure 3) to switch to horizontal picture by the menu project, or to correspond to physical button for example by the * key or by the # key or continuously by twice # key etc.. with image switching.
The present invention shows the line chart that except that vertical picture of tool prior art other increases horizontal picture and shows line chart, and as shown in Figure 2, it shows the embodiment picture of the real-time line chart of financial products for the horizontal picture of the present invention.Can learn that with Fig. 1 comparison the embodiment of the invention is hiding with its software titles row (application header), page title row (page header), command line 28, software function key, financial products title, transverse axis and longitudinal axis unit's sign (legend) etc., line chart is presented in the amplification mode, so obvious horizontal picture when showing the real-time line chart of financial products its x axle (time shaft) obviously amplify.And y axle (valency/amount axle) also amplifies a little, though reduce Word message, the person of being easy to use checks that line chart changes and difference.
The present invention removes above-mentioned real-time line chart embodiment provides vertical and horizontal picture to show simultaneously, and all the other various technical Analysis line charts (as Fig. 6) also provide vertically and laterally picture demonstration all simultaneously.The technical Analysis line chart comprise but be not limited to separated time, the time line, day line, contour, month line, year line, average line, RSI, AR, KD, MTM, MACD, PSY, VR, William's index ... etc., or all laterally picture demonstration of the figure of any tool reference significance.Information, index market behind all the other information frames such as self-selected stock quotation, news, the dish ... wait a large amount of Word messages in the embodiment of the invention, still to show with vertical picture.
And the user show by vertical picture the demonstration control that switches to horizontal picture in: the user selects in the menu project 32 in by menu 30 when screen-picture 14 shows for line chart " the switching demonstration " or carry out when switching with fast key (shortcut key).Menu 30 operations are identical with the prior art mode, be to see through the user to press the mobile device options button 1 of corresponding financial tape reading software function 1 and launch menu 30, again with on carrying out to directionkeys 24/select down the content of menu project 32, press mobile device options button 1 or directionkeys 24 at last " in key " to confirm its selection.Fast key definition can be by program decided at the higher level but not officially announced or user from ordering, it can be the undefined button of any one program in the mobile device keyboard 26.After the fast key definition, the user can not need see through the operation of menu 30 and can directly switch vertical/horizontal picture display mode with fast key.For example, by the # keyboard, then can switch to horizontal picture, or switch to vertical picture when being defined in vertical line figure picture from horizontal picture from vertical picture.Owing to laterally do not having command line 28 in the picture demonstration, user's desire is switched back vertical picture and is shown promptly and can't operate with menu 30, and with fast key control, also can be by program decided at the higher level but not officially announced or user return vertical picture by entity key arbitrarily and show from ordering when horizontal picture shows.
