WaveformGraph Properties
Installed With: Base Package
Inherits from Generic»GObject»Control»GraphChart. View the class hierarchy.
To modify the scale or cursor legend in a waveform graph 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 Cursor | Use this property to get and set the active cursor and set properties and methods on that cursor. Details |
| Active Plot | Shows which plot is active (first plot is 0). Details |
| Annotation List | Array of information about all annotations. Each array element is a cluster of annotation elements. Details |
| Cursor Legend Visible | Displays the cursor legend. This property is similar to the Visible Items»Cursor Legend item on the shortcut menu of a waveform graph control. Details |
| Cursor List | Array of information about all cursors. Each array element is a cluster of Cursor properties. Details |
| Cursor | Reference to active cursor. 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 |
| Ignore Timestamp | If FALSE (default), the x-scale includes the time stamp information from the dynamic or waveform data. If TRUE, LabVIEW sets the beginning of the x-scale to 0 instead of the value specified by t0. This property applies only to graphs 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 will never go below this value, regardless of the data in the graph or chart. Details |
| Legend:Position | Sets the position of the upper left corner of the graph legend in front panel coordinates. Details |
| Legend:Position:Left | Sets the location of the left-hand side of the graph legend in front panel coordinates. Details |
| Legend:Position:Top | Sets the position of the top of the graph legend in front panel coordinates. Details |
| Legend:Scrollbar Visible | Shows or hides the scroll bar of the plot legend. Details |
| Legend:Size | Sets the size in pixels of the graph legend. The legend expands or contracts to the right. Details |
| Legend:Size:Height | Sets the height in pixels of the graph 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 graph legend. The legend expands or contracts to the right. Details |
| Legend:Visible | Shows the plot legend. Details |
| Plot Images:Back | Sets the plot area background image, which is behind the grid lines. Details |
| Plot Images:Front | Sets the plot area foreground image, which is in front of the plot data. Details |
| Plot Images:Middle | Sets the plot area middle plot image, which is between the grid lines and the plot data. Details |
| Plot | Reference to active plot. Details |
| Selected Cursors | Displays the currently selected cursor. Details |
| Smooth Update | Draws graph with less flicker, but slightly slower. (Mac OS) LabVIEW ignores this property. Details |
