Plot Style

Plotting style is set using a ziaplot.styletypes.Style dataclass. Individual drawing axes take a style argument to specify the style of the axis and any data series it contains. To customize the style, typically start with the base Style and modify its attributes:

sty = zp.styles.Style()
sty.axis.bgcolor = '#d9f2fa'
sty.canvasw = 300
sty.canvash = 300
zp.XyPlot(style=sty)
_images/style_1_0.svg

To use the style for all plots, set the default style using ziaplot.styles.setdefault():

zp.styles.setdefault(sty)

Themes

A number of predefined styles (or themes) are built-in to Ziaplot. For example, to enable the “Taffy” theme for all plots, use:

zp.styles.setdefault(zp.styles.Taffy)

Default

zp.styles.setdefault(zp.styles.Default)
_images/style_3_0.svg

Taffy

zp.styles.setdefault(zp.styles.Taffy)
_images/style_4_0.svg

Pastel

zp.styles.setdefault(zp.styles.Pastel)
_images/style_5_0.svg

Bold

zp.styles.setdefault(zp.styles.Bold)
_images/style_6_0.svg

Dark

zp.styles.setdefault(zp.styles.Dark)
_images/style_7_0.svg

Dark Taffy

zp.styles.setdefault(zp.styles.DarkTaffy)
_images/style_8_0.svg

Dark Bold

zp.styles.setdefault(zp.styles.DarkBold)
_images/style_9_0.svg

Style Dataclass

The style dictionary is a set of nested dataclasses.
