Class SliderPlot

Create a SliderPlot instance.

The plot is returned in a QFrame widget.

Parameters:

• xvals (list) - the x values to plot
• yvals (list) - y series to plot, should be the same length as xvals
• size (tuple) - (x, y) plot size in pixels
• x_label (str) - X-axis label
• y_label (str) - Y-axis label
• x_range (tuple) - (min, max) values for the X-axis, default is to show all values
• y_range (tuple) - (min, max) values for the Y-axis, default is to show all values
• color (str) - color for the line plot - this is overridden by cvals if cvals is given.
• cvals (list, tuple or str) - For scatterplots, either a list or tuple of color values for every point, or a string to set a single color for all points. Do not use an RGB list or tuple to set a single color for all points, as that will be interpreted as intended to set individual colors for 3 (or 4 for RGBA) points. This overrides the value of color, and is not used for line plots, only scatter plots. If not given, the value of color is used.
• bg (str) - color name for the plot background. See marker:color for some color names.
• title (str) - the title of the plot
• chart_type (str) - 'line' if the chart is a line plot (default), 'scatter' if the chart is scatterplot
• shade_color (str) - A matplotlib-recognized color string that the unselected areas will be shaded
• hslider_color (str) - A matplotlib-recognized color string that the horizontal sliders will be colored
• vslider_color (str) - A matplotlib-recognized color string that the vertical sliders will be colored
• slider_thickness (int) - Linewidth of the slider lines
• slider_pick_tolerance (int) - Number of pixels the mouse click can be off and still grab the slider
• slider_moved_callback (callable) - Called when one of the slider lines has been moved. The callback will receive the SlidableLine object that was moved.
• marker (tuple) - tuple of (symbol, color, size), only used for scatter plots
  • symbol (1-character str)
    • s - square ('square', rectangle accepted)
    • o - circle ('circle' accepted)
    • ^ - triangle up ('arrow' accepted)
    • > - triangle right
    • < - triangle left
    • v - triangle down
    • d - diamond ('diamond' accepted)
    • p - pentagon
    • h - hexagon
    • 8 - octagon
    • + - plus ('cross' accepted)
    • x - x
• marker_size (int) - size of the marker
• fontsize (int or str) - size in points, or one of the following -
  • xx-small
  • x-small
  • small
  • medium
  • large
  • x-large
  • xx-large

Returns: QFrame

The QFrame widget that contains the plot

Remove any colors for points that are missing X or Y data (X or Y = None) from the list of original values. Does nothing if the point colors are not a list or tuple.

Set the color values for scatterplot points and replot

Parameters:

• cvals (list, tuple or str) - Either a list or tuple of color values for every point, or a string to set a single color for all points. Do not use an RGB list or tuple to set a single color for all points, as that will be interpreted as intended to set individual colors for 3 (or 4 for RGBA) points.

Remove any points that are missing X or Y data (X or Y = None) from the list of original values

Returns: tuple

tuple of (x-values, y-values) where each item is a list of values. Any point for which x-value or y-value is None has been removed.

Change the X and Y values of the plot

Parameters:

• xvals (list) - the x values to plot
• yvals (list) - y series to plot, should be the same length as xvals
• x_range (tuple) - (min, max) values for the X-axis, default is to show all values
• y_range (tuple) - (min, max) values for the Y-axis, default is to show all values
• replot (bool) - True of plot should be redrawn (default), False if not. False can be used if a subsequent setY is required.

Change the X values of the plot

Parameters:

• xvals (list) - the x values to plot
• x_range (tuple) - (min, max) values for the X-axis, default is to show all values
• replot (bool) - True of plot should be redrawn (default), False if not. False can be used if a subsequent setY is required.
• reset_yrange (bool) - True if the y_range should be reset, False (default) if not. It is useful to reset this if the number of datapoints is changing.

Change the Y values of the plot

Parameters:

• yvals (list) - the y values to plot
• y_range (tuple) - (min, max) values for the Y-axis, default is to show all values
• replot (bool) - True of plot should be redrawn (default), False if not. False can be used if a subsequent setY is required.
• reset_xrange (bool) - True if the y_range should be reset, False (default) if not. It is useful to reset this if the number of datapoints is changing.
