    Default Answered: Scatter Plot, Highlight Certain Points According to Flag in Data

    Answered: Scatter Plot, Highlight Certain Points According to Flag in Data


    Hi all,

    I want to figure out a way to highlight certain points in my scatter plot. I've spent some time looking into it but have found no easy way. If I was plotting data that looked like this:

    numberOne: 50, numberTwo:45, highlight:0
    numberOne: 65, numberTwo:30, highlight:0
    numberOne: 35, numberTwo:50, highlight:1
    numberOne: 25, numberTwo:45, highlight:1
    numberOne: 60, numberTwo:75, highlight:0

    So the points representing the third and fourth row above would show up as a different shape or color or size. Does anyone have any insight on this?

    thank you!

  2. I figured out a way to color the markers differently according to a flag in the data. I used a renderer in the series, here is the code:

    Code:
                    renderer:function(sprite, record, attr, index){
                            console.log(record.get('highlight'));
                            console.log(sprite);
                            var highlight = record.get('highlight');
                            var color = null;
                            if (highlight == 1) {
                                    color = "#1BE01B";
                            }else{
                                    color = "#E81717";
                            }
                                    return Ext.apply(attr, { fill: color });
                    }

    All markers and the entire line in each series are going to be the same.

    Thanks for the reply!

    Would there be a way to break up a store into two different series depending on some flag variable in the store. Like having each series represent different rows of data from the same store. I know you cant have more than one store associated with a chart
