cfchart yaxis2 title

[biene22]

Hello,

how do I set the title of a second yaxis?

There is no attribute like yaxis2title in <cfchart>  tag.

I'm working on ColdFusion 11  Standard.

regards

Go over the CFChart documentation and you'll find an attribute for yaxis2 that requires a "JSON string representation".

Adobe makes no mention of how to actually build this JSON string.  The answer is here:

Docs | JSON Attributes | Graph Objects | Scale-Y, Scale-Y-N | ZingChart

Thank you, I know the ZingChart docs.

I think my main problem is the "JSON string representation" syntax inside the cfchart attribute.

I try this, but it does not work.

yAxis2= #[{"label":{

        "text":"Label Text",

        "font-size":"20px",       

        "font-color":"red"}}]#

I think your JSON formating is wrong.  Here's an example I did a while back.  It doesn't affect the Y axis you're looking for but should point you in the right direction:

<cfset plotarea ={

                    "adjustLayout"=true,

                    "alpha"=1,

                    "margin-top"=5,

                    "margin-right"=5,

                    "margin-left"=5,

                    "margin-bottom"=0

                }>

        <cfset title = {

                    "visible"=false,

                    "backgroundColor"="##dcdcdc"

                }>

        <cfset border = {

                    "borderColor"="none"

                }>

        <cfset legend = {

                    "visible"=false

                }>

        <cfset plot = {

                    "highlight"=false,

                    "value-box"={

                        "placement"="out",

                        "connected"=false,

                        "text"="%t",

                        "font-color"="##5A5A5A",

                        "type"="all"

                    }

                }>

<cfchart

            databackgroundcolor="##dcdcdc"

            backgroundColor="##dcdcdc"

            plotarea="#plotarea#"

            title="#title#"

            border="#border#"

            legend="#legend#"

            plot="#plot#"

            chartwidth="460"

            chartheight="260"

            show3d="yes"

            name="ret.pieChartchartImg"><!--- style="#prodJSONFile#" --->

            <cfchartseries type="pie">

                <cfloop query="myqry">

                    <cfchartdata item="#numberFormat(myqry.perc,'___._')#%" value="#myqry.perc#">

                </cfloop>

            </cfchartseries>

</cfchart>

Okay, that was a good hint.

Now I have this solution:

Because it's dynamic, I get the AxisTitle from a query.

<cfset yAxis2Title= #evaluate("select_y2_axis_#n#.unit")#>

<cfchart

....

yaxis2=#{"label":{"text":"#yAxis2Title#"}}#
