SideTitles for x value on BarChartData

[tomosullivan8]

I've had a bit of an issue showing the date which I've used in as x for the BarChartGroupData and converting to the SideTitles for the group value.

It looks like the group value shows the index of the BarChartGroupData instead of the x value?

Can you let me know if there is a way to get the x value in the bottom: SideTitles?

I have been able to do it fine with the LineBarChart where it takes the x from the FLSpots, and the y value pulls through as expected for the left: SideTitle.

Could you please show me your use-case?
I know what you mean roughly, but I'm not clear about it.
Thanks!

I've included an example which should hopefully make it clear!

First, the BarChartGroupData where i've input my data to pull through onto the graph.

BarChartGroupData(
      x:  12,   /// This doesn't pull through to the X-axis (bottomTitles value).
      barRods: BarChartRodData(
          y: 72.0, /// This pulls through to the Y-axis (leftTitles value)
          width: 12.0,
      ),
    );

The FlTitlesData to show the data on the X and Y Axis.

titlesData: FlTitlesData(
        show: true,
        bottomTitles: SideTitles(
          interval: intervals,
          showTitles: true,
          textStyle: titleStyle(theme),
          getTitles: (double value) {
              return '$value'; // This doesn't pull through the X-axis from the above data.
          },
        ),
        leftTitles: SideTitles(
          showTitles: true,
          textStyle: titleStyle(theme),
          interval: 20.0,
          getTitles: (value) {
            return value.round().toString(); // This pulls through the Y-axis from above data.
          },
        ),
      ),

As you can see below, the 72 pulls through to the Y-Axis and the BarChartData with the intervals at 20.0, but the X-axis shows 0.0. instead of the 12.

I have been using the X-Axis to pull through the date in millisecondsSinceEpoch format, and it pulls through as expected for a line graph, but not for the bar chart.

Can you let me know if I'm using the BarChartGroupData incorrectly, or if there is a way around this?

I agree with you,
It will be fixed in the new version, and thank you!

Check out the 0.10.1 version.
Cheers!

Is there any way both the index and the x value can both be part of GetTitleFunction? After updating to 0.10.1 there is now no way to show the bottom tittles correctly within my application. I used the index to know where to pull the display data. I think there are valid use-cases for each piece of data.
