DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waveform display device for displaying waveform data, and more particularly to a waveform display device capable of intuitively displaying and changing the setting conditions of an arbitrary displayed waveform.

[0002]

2. Description of the Related Art A conventional waveform display device displays a waveform by setting a time, a frequency, and the like on an x-axis on a screen, and drawing a change in data with respect to the time on the y-axis.

FIG. 4 is an explanatory view showing an example of a conventional display screen. In FIG. 4, 1 is a display screen, and 2 is a waveform display screen. In FIG. 4, "a" indicates the display range of the y-axis.
The display range of the x-axis is displayed in "b".

In FIG. 4, "c" and "d" indicate a graph number and a channel number displayed on the graph.

However, in FIG. 4, waveforms of a plurality of channels are simultaneously displayed, and the set values indicated by "c" and "d" in FIG. 4 are set values for the operation target waveform selected by key operation or the like.

Here, an operation for changing the setting of the set value will be described. FIG. 5 and FIG. 6 are explanatory diagrams showing an example of a dialog box for performing an operation such as setting value change. In FIG. 5, reference numeral 3 denotes an individual setting dialog box, and in FIG. 6, reference numeral 4 denotes a collective setting dialog box.

The operator selects a waveform to be operated by operating a button or a key, and opens a dialog box for channel 1 as shown in FIG. 5, for example. In this state, the currently set upper limit value of the y-axis and the lower limit value of the y-axis are displayed as indicated by "a" and "b" in FIG.

The operator can change the display range of the y-axis by changing the upper limit or the like on a dialog box by operating a button or a key. The display color and the like of the waveform of the channel 1 can be set by pressing the button indicated by “C” in FIG. 5 and performing an operation.

FIG. 6 shows a dialog box in which the set values of all the waveforms are displayed at the same time. In this case, the set values can be checked or changed collectively.

For example, by changing the setting values indicated by "a" and "b" in FIG. 6, the display range of the y-axis of the channel 6 is changed, and the setting of "c" in FIG. 6 is also changed. By doing so, the display color of the channel 6 can be changed.

[0011]

However, in the conventional example, after confirming the graph number and the channel number corresponding to the waveform to be changed in advance, a dialog box as shown in FIG. 5 or FIG. 6 must be opened to perform necessary operations. However, there is a problem that it is difficult to intuitively change the setting conditions of the currently displayed waveform. Therefore, an object of the present invention is to realize a waveform display device that can intuitively perform an arbitrary waveform setting operation.

It is.

According to a second aspect of the present invention, in the first aspect of the present invention, a setting dialog box corresponding to the operation target waveform is displayed on the display means in response to a control signal of a setting dialog box activation request from the cursor operating means. It is characterized by doing.

According to a third aspect of the present invention, in the first and second aspects of the present invention, when the cursor stops on the arbitrary waveform for a predetermined time, a dialog box for displaying the set value of the arbitrary waveform is displayed. It is a feature.
