    <p>I'm trying to come up with a scatter plot whose range depends on the value received. The given variable self.xAxisMinimum takes in the first value of the data received. However when I run my program it reads such that, when self.xAxisMinimum = 4688 the plotspace.range starts from 5000. Given below is the plotspace settings. </p> <pre><code>CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)self.graph.defaultPlotSpace; plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(self.xAxisMinimum - 100) length:CPTDecimalFromFloat(60*60)]; plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(yAxisMin) length:CPTDecimalFromFloat(yAxisMax - yAxisMin)]; </code></pre> <p>Is it anything related to the the major interval length? I have major interval length of 180seconds. Give below is the code for the Xaxis-set's parameters.</p> <pre><code>axisSet.xAxis.title = @"Time(per sec)"; axisSet.xAxis.titleTextStyle = textStyle; axisSet.xAxis.axisLineStyle = lineStyle; axisSet.xAxis.titleOffset = 30.0f; axisSet.xAxis.majorTickLineStyle = lineStyle; axisSet.xAxis.minorTickLineStyle = lineStyle; axisSet.xAxis.majorGridLineStyle = lineStyle; axisSet.xAxis.minorGridLineStyle=gridStyle; axisSet.xAxis.labelOffset = 6.0f; axisSet.xAxis.majorIntervalLength = CPTDecimalFromFloat(180.0f); axisSet.xAxis.minorTicksPerInterval = 5; axisSet.xAxis.minorTickLength = 0.50f; axisSet.xAxis.majorTickLength = 0.50f; axisSet.xAxis.labelTextStyle = textStyle; axisSet.xAxis.labelFormatter = formatter; </code></pre> <p>So for this set up I should have had a x axis starting from (4688-100) instead of 5000. Anyone have any idea why? thanks much in advance</p>

    1. COWhat are your formatter settings? Is it rounding off the value to one significant digit? Have you inspected the actual `xRange` to see if it is being set correctly?

    2. COHello Eric, the issue lies in DecimalFromFloat. I gave an integer input to the float value and converted into decimal. Instead I changed to DecimalFromInteger. It works fine. Thanks

    3. CO@DesperateLearner: many thanks for posting your above comment: in my case, I had the same problem due to calling `CPTDecimalFromFloat` on a `double`. Your comment pointed me right at where to fix the problem. PS: you're encouraged to answer your own questions if you solve them yourself - if you post your comment as an answer, I'll be very happy to give you an upvote... :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
