I'll check other charts with Y labels for the same issue.

Description:
when the Equity Chart is resized, the labels on the Y axis for the account balance increase with each resize. The first time the increment is not much, but after many resizes it becomes more noticeable.

Steps to Reproduce:
- use any strategy that draws an line on the Equity Chart
- not highest label on y axis
- move mouse to grab the splitter ove the Equity Chart title bar
- move upwards, to increase size of Equity Chart to max height possible
- mouse up
- repeat to reduce height of Equity Chart to min height possible
- and mouse up
- note highest Y Axis label
- repeat several times

Expected:
Y Axis maximum label is the same

Actual:
Y Axis maximum increases gradually over several tries
