Of instance to Handler as a keyword to legend. On the legend() function for convenience). Which accepts a numpoints argument (numpoints is also a keyword Sake of simplicity, let's choose legend_handler.HandlerLine2D The simplest example of using custom handlers is to instantiate one of theĮxisting legend_handler.HandlerBase subclasses. Puts a legend on the current plot using the specified strings as labels. With the value in the handler_map keyword.Ĭheck if the handle is in the newly created handler_map.Ĭheck if the type of handle is in the newly created handler_map.Ĭheck if any of the types in the handle's mro is in the newlyįor completeness, this logic is mostly implemented inĪll of this flexibility means that we have the necessary hooks to implementĬustom handlers for our own type of legend key. The choice of handler subclass is determined by the following rules: In order to create legend entries, handles are given as an argument to an Accordingly, it is also referred to as 'TextMarker' by other classes. legend ( handles =, loc = 'lower right' ) plt. Contrary to its name, Legend is not just used for the plot legend, but for any kind of text particularly also for the 'Add Text' tool. add_artist ( first_legend ) # Create another legend for the second line. legend ( handles =, loc = 'upper right' ) # Add the legend manually to the Axes. plot (, label = "Line 2", linewidth = 4 ) # Create a legend for the first line. plot (, label = "Line 1", linestyle = '-' ) line2, = ax. To keep old legend instances, we must add themįig, ax = plt. To use an external table style, click Browse For External Styleand navigate to the XML file containing the style. To call legend() repeatedly to update the legend to the latest This has been done so that it is possible The legend() function multiple times, you will find that only one Whilst the instinctive approach to doing this might be to call You can then move the legend to any desired location. The legend object always appears to the right of the plot. To insert a legend using the pre-select method, Click the plot that you want to attach a legend to. Sometimes it is more clear to split legend entries across multiple The second method, or post-select method only allows you to add one legend to a single plot. To modify format of the legend text: Click on the legend object to select it, then use the buttons on the Format toolbar. Use the tools on the Format toolbar to format your text (including any substitution notation text). plot (,, label = 'test' ) for loc in : fig. Ctrl + double-click on the legend text to enter 'in-place' edit mode and insert your text directly into the legend object. subplots ( figsize = ( 6, 4 ), layout = 'constrained', facecolor = '0.7' ) ax. legend ( loc = loc, title = loc ) fig, ax = plt. plot (,, label = 'TEST' ) # Place a legend to the right of this smaller subplot. The legend is drawn outside the Axes on the (sub)figure. Specifying "outside" at the beginning of the loc keyword argument, Sometimes it makes more sense to place a legend relative to the (sub)figure legend ( bbox_to_anchor = ( 1.05, 1 ), loc = 'upper left', borderaxespad = 0. plot (, label = "test2" ) # Place a legend to the right of this smaller subplot. 102 ), loc = 'lower left', ncols = 2, mode = "expand", borderaxespad = 0. The getlegendhandleslabels() function returns a list of handles/artists which exist on the Axes which can be used to generate entries for the resulting legend - it is worth noting however that not all artists can be added to a legend, at which point a 'proxy' will have to be created (see Creating artists specifically for adding to the legend (aka. plot (, label = "test2" ) # Place a legend above this subplot, expanding itself to # fully use the given bounding box. subplot_mosaic (, ], empty_sentinel = "BLANK" ) ax_dict. Depending on the chosen image format, the available options are not the same.Fig, ax_dict = plt. You can define some parameters to customize your image file by checking the advanced options button. The plot can be exported into several different image formats. In the case of plot template (.qpt file), the graphical parameters of the plot, together with the text labels (axis, etc) are restored, but the style used to draw the curves and the scales are not saved. Save the active object as a SciDAVis template file. See the the section called “Working with templates”. You just have to add curves with the Add/Remove Curve command, but the style used to draw the curves is not kept in the template. Window and layers geometries, fonts and colors for labels and legends, etc Window and layers geometries, fonts and colors for labels and legends, etc.
