I have tried to implement ways to reduce the number of labels on the X-axis, but ApexCharts doesn’t seem to provide a way to do that with the values from the plugin inputs unfortunately . I would recommend to hide the X-axis labels and maybe create your own X-axis with dynamic data.
It is not possible to have one data series with a background color and one without. So I am afraid that it is not possible to create the chart style from your example image.
I will add your currency to the prefixes list!
