Descrizione

Description

I would love to make it possible to easily vary the width of vertical bars, or the height of horizontal bars, within a bar chart, to reflect a certain variable (such as the sample size on which that bar is based).

Why should this feature be added?

This would make it easier to visually represent an additional data point (e.g. sample size, monthly revenue, etc.), thus allowing viewers to get more context about a bar.

For example, suppose that you're showing the percentage of individuals in five political parties that support or oppose a certain measure. However, some of these parties have only a small amount of respondents. Varying the thickness of these bars by your sample size would make it clearer that some of your data points are based on a relatively small sample.

Mocks/Designs

Here is an example of what a variable-height horizontal bar chart would look like. (I created this using go.Bar() rather than px.bar(), but this involved a decent amount of additional code, including a custom legend. Being able to customize these heights via a 'bar_width' or 'bar_height' argument within px.bar would be terrific.
