Scatter Plot Huge Gap In X Axis

[techtween]

I am using FusionCharts XT with Rails 3.2. In one scenario, i'm using scatter(XY Plot) chart to present my data. There is a huge gap(marked as red box) in x axis and the max value(180) doesnt occupy the full chart. also i'm not getting the X axis values(140 to 180) displayed horizontally.What possible reason could that be?

 

 

My xml builder file is as follows(i've also attached a screenshot of my chart for yours understanding),

 

xml = Builder::XmlMarkup.new

xml.chart(:palette=>'2', :caption=>'', :subcaption=>'', :showLegend=>'1', :showNames=>'1', :xAxisMinValue=>'140', :xAxisMaxValue=>'180', :adjustDiv=>'0', :numDivLines=>'22', :divLineColor=>'b2dde3', :divLineThickness=>'2', :alternateHGridColor=>'edfdff', :yAxisMinValue=>'2.0', :yAxisMaxValue=>'4.4', :yAxisValueDecimals=>'1', :decimals=>'1', :forcedecimals=>'1', :bgColor=>"196bdb,b2dde3", :bgAlpha=>"10,40", :showValues=>'140', :labelStep=>'2') do

# Run a loop to create the <category> tags within <categories>

xml.categories(:verticalLineColor=>'b2dde3', :verticalLineThickness=>'1') do

xml.category(:label=>'140', :x=>'140', :showVerticalLine=>'1')

xml.category(:label=>'142', :x=>'142', :showVerticalLine=>'1')

xml.category(:label=>'144', :x=>'144', :showVerticalLine=>'1')

xml.category(:label=>'146', :x=>'146', :showVerticalLine=>'1')

xml.category(:label=>'148', :x=>'148', :showVerticalLine=>'1')

xml.category(:label=>'150', :x=>'150', :showVerticalLine=>'1')

xml.category(:label=>'152', :x=>'152', :showVerticalLine=>'1')

xml.category(:label=>'154', :x=>'154', :showVerticalLine=>'1')

xml.category(:label=>'156', :x=>'156', :showVerticalLine=>'1')

xml.category(:label=>'158', :x=>'158', :showVerticalLine=>'1')

xml.category(:label=>'160', :x=>'160', :showVerticalLine=>'1')

xml.category(:label=>'162', :x=>'162', :showVerticalLine=>'1')

xml.category(:label=>'164', :x=>'164', :showVerticalLine=>'1')

xml.category(:label=>'166', :x=>'166', :showVerticalLine=>'1')

xml.category(:label=>'168', :x=>'168', :showVerticalLine=>'1')

xml.category(:label=>'170', :x=>'170', :showVerticalLine=>'1')

xml.category(:label=>'172', :x=>'172', :showVerticalLine=>'1')

xml.category(:label=>'174', :x=>'174', :showVerticalLine=>'1')

xml.category(:label=>'176', :x=>'176', :showVerticalLine=>'1')

xml.category(:label=>'178', :x=>'178', :showVerticalLine=>'1')

xml.category(:label=>'180', :x=>'180', :showVerticalLine=>'1')

end

 

 

# Run a loop to create the <set> tags within dataset for series 'Accepted'

xml.dataset(:seriesName=>'Accepted', :color=>'008000', :showPlotBorder=>'1', :anchorRadius=>'4', :anchorBgColor=>'008000') do

accepted.each do |accepted|

xml.set(:y=>accepted.gpa_lsdas, :x=>accepted.lsat)

end

end

# Run a loop to create the <set> tags within dataset for series 'Waitlisted'

xml.dataset(:seriesName=>'Waitlisted', :color=>'ffd700', :showPlotBorder=>'1', :anchorRadius=>'4', :anchorBgColor=>'ffd700') do

waitlisted.each do |waitlisted|

xml.set(:y=>waitlisted.gpa_lsdas, :x=>waitlisted.lsat)

end

end

# Run a loop to create the <set> tags within dataset for series 'Rejected'

xml.dataset(:seriesName=>'Rejected', :color=>'FF0000', :showPlotBorder=>'1', :anchorRadius=>'4', :anchorBgColor=>'FF0000') do

rejected.each do |rejected|

xml.set(:y=>rejected.gpa_lsdas, :x=>rejected.lsat)

end

end

end

I'm having the same problem. What is causing the gaps between the categories and the axis limits??

After quite a bit of head scratching I solved my problem. I was rounding the category values, and not the xAxisMin / xAxisMax values. Apparently, if there's any difference between the first category and the xAxisMin, or the last category and the xAxisMax, then you will have this problem.

Hi,

 

As you have mentioned, if you are defining the range of values for X-Axis ( xAxisMinValue, xAxisMaxValue) and the data points are not fully spread over this range of values, you will get the blank space at the right most side of the chart.

 

So, you need to apply the categories and the X-Axis min and max values as per the data set range.

 

Hope this helps !
