Scaling seems weird please help

[uberphoebe]

I am drawing a bar graph  and the max value is "9". Three value 9,0,3

The y scale is showing 100.....

If I switch max scale to 9 it works but autoscaling (which I want) is going wonky,

 

Any ideas....please?

One possibility would be that you are letting the chart to initialize with random data and after that we are not resetting the min/max to the real data scale.

Can you clarify when are you passing the data to the chart? Can you post a small sample page that duplicates the issue you are experiencing?

Ok lets say

gn="car"

gl="old,new"

pos="24,3"

neg="18,23 

 

 

 

var chart3

    function loadGroupChart(gn,gl,pos,neg)

{

var gla=gl.split(",");

var posa=pos.split(",");

var nega=pos.split(",");

var i=gla.length;

chart3 = new cfx.Chart();

chart3.setGallery(cfx.Gallery.Bar);

var data = chart3.getData();

data.setSeries(2);

data.setPoints(i);

//load data points

for(var j=0;j<i;j++)

{

data.setItem(0, j, posa[j]);

data.setItem(1, j, nega[j]);

// Series  X axis labels

chart3.getAxisX().getLabels().setItem(j,gla[j]);

}

// Series  data name

chart3.getSeries().getItem(0).setText("Positive");

chart3.getSeries().getItem(1).setText("Negative");

//recalculate scales

chart3.recalculateScale(true);

// Series  X axis labels

chart3.getLegendBox().setVisible(true);

chart3.getAxisY().getGrids().getMajor().setVisible(true);

chart3.getAxisY().getGrids().getMinor().setVisible(true);

document.getElementById('ChartDiv3').innerHTML = "";

document.getElementById('ChartDiv3').innerHTML = "Analysis by "+gn;

var divHolder = document.getElementById('ChartDiv3');

chart3.create(divHolder);      

}

You are passing strings in the calls to data.setItem instead of numbers, please try this

data.setItem(0, j, Number(posa[j]));

data.setItem(1, j, Number(nega[j])); 

Also, possibly a typo when creating the simplified sample, you are not using neg when splitting into nega.

Finally, you can remove the recalculateScale call as it is not needed.

Exactly the problem. Thankyou
