How to use a date/string for the X value

[hdoria]

The new Charts version only accepts double for the x value. How can I use a date (or string) for the X value?

ChartDataEntry: public init(x: Double, y: Double)

This issue talks about how to use axis value formatters to use strings as axis labels.

However, I'm still confused about how I can put one string under each bar in a bar chart, instead of the strings lining up with axis gridlines.

@Carielle I don't understand why you said this. In ChartsDemo, the x axis label is centered in each bar's center.

Hey @hdoria how did you get on? Did you find the new IAxisValueFormatter in Charts v3.0.0 to customise the text to a string?

Just in case: create one a subclass of IAxisValueFormatter, implement func stringForValue(_ value: Double, axis: AxisBase?) -> String and return the string you want there then set your xAxis.valueFormatter to it.

Let us know how you get on and whether to close this issue.

@madhikarma did exactly like you said. Thanks.
