Hello, Everyone I need bell curve chart for visible three data's(two constant data one variable data) in ignition perspective ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/b/ab2e5c5cb438c139a5792608f54fcfad7b1d17e9.jpeg) look like this ---

what does it look like if you just plot the data in a xy chart? ---

I have two y axis values like (01,50) and then one x axis with variable values like(2,3,11,22,33,44) , So i highlight the x value when x values is change and between two y axis , thanks ---

The xy chart should work fine for this. Your range axis will be your process voice, 0 to whatever the max value is. The domain is simple the mean minus four times the standard deviation to the mean plus four times the standard deviation. ---

Are you looking to make an 'ideal' distribution graph, or just a histogram of your data? ---

@JordanCClark I will show data in the chart for selected datetime range of the users, so i need ideal graph, the above graph mean is change for my chart because the mean shows the average of selected data of datetime ---

so are you looking for something that turns your data into a distribution. (thats not always possible) or is you data a distribution and you just want to display it. ---

@victordcq Yeah, I want to display the data in xy chart with three axis. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/6/265e731f55b3faaa761b26711d20e34596fa250b.png) i am working with this now. ---

It looks like you want an X-Bar R chart. There are modules that do that, along with lots of SPC goodies. Building a fully functional X-Bar R chart from Perspective components is possible. ---

Hi, one question this module is free of cost or we need to pay for licenses like that? ---

It's not only free, but open-source. As shown by the license on that GitHub page. So you can not only deploy it freely, but alter it and deploy your own modifications freely. ---

Thanks for the update.. Is it worth to implement open source module in to ignition? Any disadvantages there? I am to new to this topic that’s why ---

1. Yes, it is economical, and you are not vendor-locked for features nor for bug fixes. (But you might have to do it yourself.) 2. Yes, the ability to purchase support for open-source software varies, and can change with little notice.
