I'm struggling with charting some data in SSRS with a column chart. The data in my SQL select returns a number of devices and their battery level as a decimal e.g
Device 1, 90%
Device 2, 90%
Device 3, 80%
Device 4, 30%
I have rounded the real battery percentage so the view can only ever output, 100 to 0 in 10% chunks.
I then have a column chart in SSRS which counts the number of devices which fall into each 10% and charts them. The issue is that in this example only the columns for 30%, 80% and 90% appear, along with their headings. What I would like is to show all of the titles from 0 to 100 but only draw a column in where there is a record.
I've tried forcing the scale with 10 increments but that doesn't help. I guess this question is two fold. Is there a way that I can force SSRS to display the column headers even though there is no data for those specific headers? Any other way that this can be achieved if not?
I have a feeling that I might need to do something in the select to force the data to include these but not sure how I might do that.
Here is an example of the chart currently:
As you can see, I only get column titles for 30, 80 and 90.

I have created a line chart which has the date as X-axis and Y-axis as calculated median value and its grouped according to "FileName". Problem is that some of the "FileName" has same median values which makes line overlap thus not able to see all the lines. Attached image shows only 5 lines but there are total 10 lines. After running query I found out other 5 has 50 as the median which makes it overlap with one of the line.
I tried using transparency and secondary axis but wasn't able to achieve the desired result. Is there any other solution to try out ? Thanks!
This is more of a data presentation issue than something specific to SSRS. If you are stuck on using a line chart, then I've only used two options:
1) Increment lines to different widths. For example, in a chart with 3 lines, the width is set to 5,3,1 pts.
2) Change the values insignificantly to offset the lines. Obviously this depends on the data being visualized as shifting the line slight (multiply by 0.1) may be allowable or highly discouraged depending on your situation.
Trying to do either option with 10 lines (and up to 5+ stacking) is not going to be very good.
I think Viking is right and you might want to check out other visualization options. Grouped column charts perhaps or just split your chart into multiple charts on the page (i.e. four separate trend charts)
I'm trying to visualize the SO Developer Survey in Tableau. I have a side-by-side stacked bar chart. On the x-axis I have job satisfaction, separated by gender. (So, columns: job satisfaction, gender, both are dimensions). On the y-axis I have "most important aspect of a job opportunity" (So, rows: measure values, with each value being a COUNT).
I would like each bar to total to 100% so for each value in measured values I have set the quick table calculation to "Percent of Total" and am computing using cell, but when I do so, every value appears to be equal/100% within the bars.
Can anyone tell me what I am doing wrong? Each value should be some percentage, all totaling up to 100%.
I was trying to follow this tutorial: http://kb.tableau.com/articles/howto/stacked-100-percent-bar-chart
Percent of total computed by cell will always give you 100%. Tableau is telling you that each cell represents 100% of the value for that cell. You will need to change your compute using to get the correct answer.
Here is an example using the "superstore" data set that ships with Tableau. To calculate the percentage breakdown for each region I use the Percent of total table calculation and calculate it by "Pane" which means that the percentage is showing me a value per region (so, "technology" represents 33.999% of sales in the "central" region):
I have a bar chart that show the count of number of models for each agency,
The problem is that I have a large difference between the values that makes the report to look not so good.
Does anyone have any ideas of a good way to resolve this problem?
Have you considered using a logarithmic scale?
With your chart Right-click the y-axis, and click Vertical Axis Properties.
In Axis Options, select Use logarithmic scale.
Leave the Log base text box as 10 (this is the scale most commonly used by logarithmic charts)
This will display a chart with a scale that goes up by a factor of 10 for each ‘unit’ up, so the distance between 1 and 10 is the same as that between 100 and 1000.
For example the shown dataset is displayed as this chart when using the logarithmic scale
This method is a simple and recognised way to clearly show values of widely different scales.
Update
If want an indicative bar for the vales that are 1 then you could use the expression
=iif(Fields!val.Value = 1, Fields!val.Value * 1.1, Fields!val.Value)
To make all values that are 1 equal to 1.1 so showing a tiny bar appearing a the bottom of the chart, as seen here
Unfortunately I don't know of a way to change that first 1 to a zero (formatting-wise). This is partly because you are now using a logarithmic scale and zero and negative values don't really exist. This is due to a fundamental property of logarithms in mathematics, that
LOG10(10)= 1
LOG10(1) = 0
LOG10(.1)=-1
Therefore, when you perform a log10 of zero, it just doesn't exist.
EDIT: The chart is fixed when I use a stacked chart instead of a stacked percentage chart, but this still doesn't tell me what is wrong with using the percentage chart.
I have a stacked percentage chart which is going from 0 to 10000% instead of 0 to 100%. It appears as if the values are formatted correctly (they add up to 1.01 due to rounding), and even dividing all the values by 100 in the query does not change it.
This is how the chart renders:
with the following Vertical Axis Properties:
I have a table below (with identical number formatting but with 2 percentage points), however that displays as expected:
Finally, here is the raw data set with an additional sum column not reflected in SSRS:
Has anyone come across this issue before? If I manually set the range of the chart from 0-100% (0-1) I can only see that bottom blue series.
Yep. I've seen exactly this. The numbers that the percent chart axis generates are in the range 0 to 100. But when you apply the number formatting as a percent, then the numbers are multiplied by 100 for display.
The trick to fix/work around this is to set the display format to only add the percent sign, not really format the number as a percent. Happily, this requires just one character:
In the Number format for the axis, switch the Category to "Custom." If you just switched from Percentage, you will see something similar to 0%.
Insert a backslash before the percent symbol: 0\% to indicate that you need a literal percent symbol, not to format the number as a percent (multiplied by 100.)
Voila.
I am having a problem with getting a stacked area chart to display the right data in SSRS 2005.
On my Y axis, I want a scale from 50% to 100%.
On my X axis I have a set of dates formatted in a style that was necessary for the report (so varchar).
My data consists of 3 data fields which are decimal numbers and contained between 0 and 1, each with a specific date.
My problem is the scale of the Y-axis. I have set the maximum value to 100, the minimum to 50, the interval to 5, and the format to "p" for percentages.
On the preview in the layout tab, this all appears fine (Y-axis starting at 50% up to 100%).
However whenever I generate an actual report it goes from 5000% to 10000% for some reason. I have no idea how this is happening and it completely ruins the report.
I have tried tinkering in the properties for several hours but to no avail.
If this has happened to anyone and they have found a solution, or if anyone has any suggestions I would be very grateful.
Thanks.
When you use percentages, everything factors by 100.
If you want to format and display a value as 50% , it needs to be 0.5 unformatted. Percentages are therefore values between 0 and 1.
Excel and pretty much every other tool works that way.
If your values are all stored as percentages already, then you might just want to append the % symbol at the end of your values. Or better, divide everything by 100.
50 per cent means just that anyway; it means 50 per hundred (cent means 100) so 50/100 is another way of writing 50%.
