No circle is drawn on a line chart when there is only one data. (version 3.2.2 only) #3848
Description
What did you do?
I updated the Charts library from 3.2.1 to 3.2.2.
What did you expect to happen?
When a line chart has just "one" entry data, the chart shows a circle to indicate the data.
v3.2.1 (with highlight / It draws a circle. correct.)
v3.2.1 (without highlight / It draws a circle. correct.)
What happened instead?
No circle was drawn on the chart.
*chartDataSet.drawCirclesEnabled is always set as TRUE.
The problem happens when there is only "one" entry.
(But if there are more than two entries, it works fine.)
v3.2.2 (with highlight / No circle was drawn. wrong)
v3.2.2 (without highlight / No circle was drawn. wrong)
*When I switch it back to the version 3.2.1, it draws a circle (expected behavior).
