+`type: boolean`
+
+The `disableInlineStyles` prop allows Victory components to work better with CSS classes or styled-components. By default, Victory provides inline styles to chart components, which will override any conflicting CSS styles. This flag will remove the inline styles, making it easier to provide custom styling for components via CSS.
+
+If this prop is passed to a chart type (e.g. `VictoryBar`), it will apply to all data and label components for that chart.

+const StyledBar = styled(Bar)`
+  fill: purple;
