To modify the scale legend in a waveform chart programmatically, create Property Nodes for each element of the legend you want to modify. For example, if you want to modify the scale label, right-click the string element in the scale legend and create a Property Node for that element.
| Property | Description |
|---|---|
| Active Plot | Gets or sets the active plot. After you get or set the active plot, you then can set properties or invoke methods that affect only the specified plot. Details |
| Digital Display(s) Visible | Indicates whether the digital displays for the chart are visible. Details |
| Digital Display[] | Reference(s) to the digital display(s). Details |
| History Data | Array of the history data of a chart. Wire an empty array to this property to clear the chart history. Details |
| Ignore Attributes | If FALSE (default), the plot names in the plot legend and the scale names on the graph automatically adapt to the plot names and scale names in the dynamic or waveform data attributes. If TRUE, the plot names and scale names do not adapt to the dynamic or waveform data attributes. Change this property to TRUE if you want to change the plot names and scale names. This property applies only to graphs and charts with dynamic or waveform data. Details |
| Legend:Autosize | If TRUE, the plot legend automatically resizes to the width of the longest plot name visible in the legend. Details |
| Legend:Disable | Disables the plot legend at run time. Details |
| Legend:Number of Rows | Sets the number of rows in the plot legend. Details |
| Legend:Plot Minimum | Sets the minimum number of plots to keep in the plot legend. The number of entries in the plot legend never goes below this value, regardless of the data in the graph or chart. Details |
| Legend:Plot Visibility Checkbox Visible | Determines whether to show or hide the Plot Visibility checkbox on the plot legend. Use the checkbox to select which plots you want to display in the plot area. Details |
| Legend:Position | Sets the position of the upper left corner of the chart legend in front panel coordinates. Details |
| Legend:Position:Left | Sets the location of the left-hand side of the chart legend in front panel coordinates. Details |
| Legend:Position:Top | Sets the position of the top of the chart legend in front panel coordinates. Details |
| Legend:Scroll Position | Gets or sets the position of the scroll box in the scroll bar of the plot legend. To set the position, wire a numeric value to this property that represents the plot number to which you want to scroll. LabVIEW places the plot you specify as the first visible plot in the plot legend. To set the scroll bar to the first plot, specify a value of 0. To set the scroll bar to the second plot, specify a value of 1, and so on. Details |
| Legend:Scrollbar Visible | Shows or hides the scroll bar of the plot legend. Details |
| Legend:Size | Sets the size in pixels of the chart legend. The legend expands or contracts to the right. Details |
| Legend:Size:Height | Sets the height, in pixels, of the chart legend. The legend expands down, and truncates the height to the closest value that displays an integral number of plots. Details |
| Legend:Size:Width | Sets the width, in pixels, of the chart legend. The legend expands or contracts to the right. Details |
| Legend:Visible | Determines whether to show or hide the plot legend of the waveform chart. Details |
| Plot | Reference to active plot. Details |
| Stack Plots? | Returns TRUE if the plots are stacked and FALSE if the plots are overlayed. Details |
