Adding Values to tooltip, color changing, disableing the point.

[Neil]

Hey,
saving Your time I`ll try to ask several questions in one thread.

 So I`m trying to do the same with the tooltip - to display something in addition to the default tooltip.

So default is that the tooltip displays the value of the point, I added to display the date like this:

tooltip: {
                            visible: true,
                            format: "{0:N0}",
                            template: "#= dataItem.Date #"
                        }


But then it only shows the date but not the value any more. Any advice ?

Ideally I would like to see the name value and date in the tooltip.

name being written when adding the series :   
 series:
                        [{
                            field: "Value1",
                            name: "GP3-PT-270517.PV_IND"
                        }, 
                        {
                        field: "Value2",
                        name: "Name2"
                        },

Interesting thing is that when i generate json file and the field name is "GP3-PT-270517.PV_IND" it doesnt work, hence i had to rename it to Value1, Value 2 and so on. Why is that ? json doesnt like " -, , ._" ? 

I couldn`t find how to change the colour of the lines on my chart ? hwo to change the width of the line and how disable the round circles on the line.

Thank You in advance, 
Much Aprech,
N

Hi Neil,

You could customize the text in the tooltip via dataItem variable in the template. For example: 

tooltip: {
   visible: true,
   template: "#= dataItem.name # - #= dataItem.date #"
}

You can configure the line chart via its configuration options:

• color property - changes the color;
• width property - changes the width of the lines;
• markers property - configuration of the markers.  

Indeed, this is a valid JSON, but it is not recommended to use any of these symbols ".", ",", "%", "-" in the name of the objects, because the DataSource internally uses regular expressions.
