can barely understand. give more details and we will update.
if you change your data set, call chartData.notifyDataChanged
for drawing values, check out ChartsDemo multiple bar chart.

let take an example , if i have an data set {"jan", "feb" ,"mar" ,"apr" , "may", "june"}. and i set the graph as look and feel for setting 3 bar as a group.

2 - if data set value {"jan", "feb" ,"mar","apr" ,"may" ,"june" ,"july" ,"aug" ,"sep"} , then my whole view of graph is disturbed , and all bars are overlaped .

give a screenshot. take a look at multiple bar chart btw. make sure bar space, group space, bar width formula sums to 1.0

    float groupSpace = 0.08f;
    float barSpace = 0.03f;
    float barWidth = 0.2f;
    // (0.2 + 0.03) * setCount + 0.08 = 1.00 -> interval per "group"

this graph comes when data set value comes more than - 4

[Raj14737]

this graph come when dataset value come - 4,

        let groupSpace = 0.16
        let barSpace = 0.05
        let barWidth = 0.23

startPoint = 0

cell.viewSummaryBarChart.xAxis.axisMaximum = Double(startPoint) + 1.6 * Double(groupCount)

and gropucount -- 4

[Raj14737]

this graph comes - when i used this

let groupSpace = 0.16
let barSpace = 0.05
let barWidth = 0.23
startPoint = 0

and when i used this method to found groupwidth -

let group_space = chartData.groupWidth(groupSpace: groupSpace, barSpace: barSpace)

[Raj14737]

i want to that it set perfectally , it dont be depended how many dataset it comes . either it be 4 or it be 6 .

I barely understand. check out charts demo, play with it first.
