Methods

NameSummary
static AutoScaleXCreates an action that automatically adjusts the horizontal axis scaling of a plot using the specified X-axis configuration.
static AutoScaleYCreates an action that automatically adjusts the Y-axis range of a plot to fit its data within the specified RenderPack.
static AutoScaleAllCreates an action that automatically adjusts all axes in a plot to fit the current data.
HideAllYAxisHides all Y-axis elements by setting their visibility to false.
CreateAxisWithTimeStampConfigures the plot to use a bottom axis displaying date and time ticks, and sets the axis range to cover all possible date values.
AxisStyleConfigures the plot axes and grid to hide tick labels, remove tick marks, and display the plot without a frame.
CreateAxisWithPointsRemoves the existing bottom axis from the plot and creates a new bottom axis with updated settings.
SetXAxisColourSets the colors for the X-axis labels, ticks, and frame to predefined values for improved visual clarity.
ClearLabelsRemoves all label markers and associated text from the plot and clears the label collection.
ClearAxisCrosshairsRemoves all axis-related crosshair lines and markers from the plot and clears the crosshair collection.
ClearAxisLinesRemoves all axis lines from the plot and disposes of their associated resources.
ClearContentRemoves all plot data, controls, and labels from the current view, releasing associated resources.
YAxesSetupConfigures the Y-axes of the plot using the specified axis names and colors. Existing Y-axes are removed and replaced with new right-side axes corresponding to the provided data.
ManualScaleYSets the Y-axis limits of all axes in the plot to the range 0 to 100.
InitializeGenericPlotLinesInitializes and configures up to 16 plot lines in the chart using the provided data and UI creation logic, assigning each plot line to the appropriate Y-axis and setting up the X-axis as...
InitializeScatterPlotLinesInitializes scatter plot lines using the provided collection of observable data series.
InitializeLinesForScatterObservablesPointsInitializes plot lines for scatter plots using a collection of observable point sequences.
InitializeSignalPlotLinesInitializes plot lines for signal data using the provided collection of observables.
InitializeDataLoggerPlotLinesWithPointsInitializes plot lines with data points for the data logger using the provided observables.
InitializeLinesForSignalPointsInitializes plot lines for a single set of signal points using the specified data tuple.
InitializeLinesForSignalObservablesPointsInitializes plot lines for a collection of signal observables, configuring each line to display its corresponding data points on the plot.
InitializeLinesForScatterPointsInitializes and adds a new scatter plot line to the chart using the specified data points and axis.
InitializeControlMenuInitializes the control menu with the specified chart object settings, replacing any existing items.
InitializeAxisLinesInitializes and configures axis line elements for the plot, adding them to the plottable collection if available.
UpdateChartObjectsCollectionUpdates the ChartObjectsCollection from current plot lines. Called automatically after plot initialization.
GetLineUnderMouseGets the axis line located under the specified mouse coordinates, if any.
