Hi, Is there any way to show tooltip for the lines when we mouse over on it. (note- without enabling the bullet option) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/5/c5fc9df2e6c16754a17a268a0f8231d458953e7b.png) ---

You can achieve this by setting the following two properties to 0. Unfortunately you have to enable bullet option. `.bullets>fill>opacity` `.bullets>stroke>width` or `.bullets>stroke>opacity` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/0/f018015cc5ed3a8d739a88dd6502e331b31848ec.png) However, I have a concern: how is the user supposed to know where to hover to see the tooltip? Any specific reason to disable bullet?) ---

1. Remove the grid `[x/y]Axes>[*]>appearance>grid>opacity = 0` 2. Space at the each end of x axis I don't know parameters to do it. Let's see if anyone knows how to achieve this. One workaround is adding samples in `dataSource` with value `null` 3. Style labels `.bullets>[*]>label>text = [font-Size:20px bold]{value}` _value will be key from dataSources_ You can refer to amCharts documentation for more options [Text styling – amCharts 5 Documentation](https://www.amcharts.com/docs/v5/concepts/formatters/text-styling/#:~:text=Formatters-,Text%20styling,-Any%20text%20in) ---

Can you share the value of `series>[*]>data>y` in the XY Chart? As I mentioned in my post, > [@Ujwal\_Wankhede](#): > > `.bullets>[*]>label>text = [font-Size:20px bold]{value}` > _ **value** will be key from dataSources_ ---

Hi, one question If data points are more then enable bullets makes the chart very slow sometimes web page gets hang. Is there any option to fix this issue? ---

I haven't personally encountered a situation where the page becomes unresponsive due to enabling bullets. Can you tell me the total datapoints in your dataSources? If you have a very large dataset, consider reducing the number of data points by aggregating or sampling the data. ---

Hi, Sorry for delay response i am not feeling well. Yes large data points is issue nearly i have 3000 rows I am using it as dataset. Converting them to json might reduce rendering little?
