KB15062: Unable to specify separate line styles for each needle on a gauge graph in MicroStrategy Developer

SYMPTOM:
 
When there is more than one needle on a gauge graph in Strategy Developer, the user is unable to specify separate line styles for each needle.
 
STEPS TO REPRODUCE:
 
Follow the steps below to reproduce this issue in the Strategy Tutorial project:

• Create a report with the 'Region' attribute and the metrics 'Profit' and 'Revenue.'
• Execute the report as a graph, choosing the Gauge Graph (Advanced > Gauge > Gauge Graph.)
• If necessary, show the second metric's needle (right-click on the data point, choose 'Graph Options,' and uncheck 'Hide Marker Needle.')
• Right-click on one needle (or the legend marker) and select 'Format Gauge Needle' (or 'Format Legend Marker.')
• Select the Line tab and choose a 4pt thickness, solid, red line.
• Click OK, and notice that the line style has now been applied to both needles, as shown below:
  

CAUSE:
 
This is a known issue in Strategy Developer.
 
WORKAROUND:
 
Instead of using Line style to customize the needle, utilize the 'Fill' tab and apply a pattern or a picture to each individual needle:

• Create a gauge graph with two needles, as described above.
• Right-click on the data label for one metric and select 'Format Legend Marker.'
• Change the Line tab settings to transparent and click Apply.
• Select the 'Fill' tab.
• Click the 'Pattern' button.
• Change the foreground color to white.
• Change the background color to black.
• In the main window, select the Row 4 Column 5 pattern (angled bricks, or similar).
• Click OK twice.
• Format the second data label to a solid color (blue) with the line tab set to transparent.
• The needles are now different colors, as shown below:
