Adding a new entry on a line chart (in between existing entries) causes chart to behave weird.

I am trying to create a chart in which entries can be added and removed dynamically.

The problem I'm facing is that when I add new entries at a smaller xAxis value than the previously existing entries, they graph reflects random lines.

If I add a new entry where the xAxis value is bigger than the previous values, it works perfectly. Deleting existing entries is also working fine.

Following are the steps with screenshots:

Step 1. **Initial chart**

Step 2. **Adding a value at 10.30**

Step 3. **Adding a value at 11.30**

Step 4. **Now when I add a new value at 11.00, since the dataSet already has a value for 11.30, the graph starts showing random output.**

Now when I delete this value which I added last, the chart becomes accurate again.

I could clear the values altogether and create a whole new data set whenever a new entry is to be added but that's just unnecessary iterations over the data which has to be shown. Since there are methods to add entries to the chart, I assume there is a way to add entries in between existing ones.

Could you please guide me towards how could I achieve the required behaviour?

Thanks in advance!
