Wrong format for values in the chart

[julian-nunezm]

Hi there.

We are using the chart library to create some charts for DPC. We received feedback from the person who is checking those charts.

There are two issues:

1. If a value of the datasets is 7.0 the charts print that value as 7 in the chart but the value must be 7.0.

2. The values that are shown in the charts (i.e. in every bar in a bar chart) don't have a thousand separator character (,). In this case the value should be 4,987.

As we are using the SDP library, is there any way you can help us with that? Also, these issues would apply for bar and line chars.
