SVG Bar Chart within a table

[Sdg8481]

Hi, from searching on the internet i found this brilliant code for adding a barchart into a standard table.

However, i can see that ChartScale is hardcoded (at 10,000), however all of my values in the table vastly differ and are independent of each other, therefore a fixed scale doesn't work.

How can i adapt the code below so that the Chart Scale is relative to the Maximum value for each row ('Area|Attribute') in the table. Apologies in advance, i'm a complete DAX novice.

Dynamic Chart = 
var BaseURL = "https://chart.googleapis.com/chart?"
var ChartType = "cht=bvs"
var ChartScale = "&chds=0,10000"
var ChartSize = "&chs=150x150"
var SeriesColour = "&chco=000000"
var ChartData = "&chd=t:" & CONCATENATEX('D - Current Year Data By Week (for Trend)','D - Current Year Data By Week (for Trend)'[zValue (week) as Measure], ",", 'D - Current Year Data By Week (for Trend)'[Reporting Thursday])
return IF(HASONEVALUE('D - Current Year Data By Week (for Trend)'[Key1: Area|Attribute]), BaseURL & ChartType & ChartScale & ChartSize & SeriesColour & ChartData)

Thanks

Stu

what happens if you use 

var chartScale = ""

instead?

Hi, thank you that definately helps, especially for when the numbers are relatively small. However, when BOTH numbers start to get large there appears no difference in the bar size.

As you can see in the example below, it all seems to work, but when both numbers are above 100, but still have a big difference between them the bar sizes show equal ... when clearly there is a difference.

That probably means that internally the SVG defaults the chart scale to 100 if no value is given.

In that case you need to provide a dynamic chart scale based on your largest number.

Say, your numbers a and b are 4300 and 3500.  Then your chart scale should be a "1"  followed by 

(int(LOG10(max(number a,number b))+1) "0"  strings.

Thank you that really helped. Your idea of getting the maximum did the trick. Thank you
