Column/Bar chart performance

[haruki_zaemon]

I took the performance page and modified it slightly so as to be able to render different types of charts with large datasets (see https://gist.github.com/harukizaemon/6f994fdf178415cb70c838f37d55f660).

On my laptop, I get about 50ms to render 100k data points as a line chart. And about 800ms (often longer) to render a column chart. Bar and Column seem to be the slowest by a long way.

Is this to be expected? Is there anything that can be done to improve the performance? I’m trying to view a histogram (from frequency data).

@haruki_zaemon,

This is expected as rendering of Bar/Column chart is relatively slower than line charts as it takes more processing.
