The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Macro for a bar chart.

Asked by capterdi in Microsoft Excel Spreadsheet Software

Hi EE,

I have a set of data that I would like to be represented in a bar chart, via the executing of a macro. Right now I have 6 different variables, but let´s talk only of 2 of them, so later, once the macro is written, I would follow it in order to get the rest of the variables done.

Starting on row 2, on column “A” I have the description or name of the variable. On column “B”  I have the value of the corresponding variable, expressed as percentage with 2 decimals.

Example for the first variable:

The number found on “B2”  must be evaluated according to the following:

“B2” value range                  Grade assigned in %                               Color for bar in chart

less than 0.9350                  0                              red
0.9350 – 0.9395                  0 – 20.0                                        red
0.9396 – 0.9500                  20.1 – 50.0                        orange
0.9501 – 0.9557                  50.1 – 65.0                        yellow
0.9558 – 0.9589                  65.1 – 85.0                        light green
0.9590 – 0.9650                  85.1 – 100.0                        dark green
more than 0.9650                  100.0                              dark green

Then, according to the grade obtained, and the corresponding color, I would like the representation in the bar type chart, which on the abscissa axis would have the scale 0 to 120 % and on the ordinate axis the scale would depend on the amount of different data that is being analyzed. In this case we have 2 variables to chart.

Examples for the interpolation:

if  the value on “B2” is 0.925 then the grade is 0.00% and the bar is red.
if  the value on “B2” is 0.937 then the grade is 8.89% and the bar is red.
if  the value on “B2” is 0.942 then the grade is 27.0% and the bar is orange.
if  the value on “B2” is 0.953 then the grade is 57.82% and the bar is yellow.
if  the value on “B2” is 0.957 then the grade is 72.80% and the bar is light green.
if  the value on “B2” is 0.960 then the grade is 87.58% and the bar is dark green.
if  the value on “B2” is 0.970 then the grade is 100.0% and the bar is dark green.

About the graph: the bar should be proportional to the grade assigned, and also the value of the grade should be shown on it.


For the second variable:

The number found on “B3” must be evaluated according to the following:

“B3” value range                  Grade assigned in %                                           Color for bar in chart

more than 5.00                                  0.0                              red
5.00 – 4.70                        0.0 – 20.0                                        red
4.69 – 4.00                        20.1 – 50.0                        orange
3.99 – 3.60                        50.1 – 65.0                        yellow
3.59 – 3.40                        65.1 – 85.0                        light green
3.39 – 3.00                        85.1 – 100.0                        dark green
less than 3.00                        100.0                              dark green

Examples of interpolation:

if  the value on “B3” is 6.0 then the grade is 0.00% and the bar is red.
if  the value on “B3” is 4.8 then the grade is 13.33% and the bar is red.
if  the value on “B3” is 4.2 then the grade is 41.33% and the bar is orange.
if  the value on “B3” is 3.7 then the grade is 61.18% and the bar is yellow.
if  the value on “B3” is 3.5 then the grade is 74.53% and the bar is light green.
if  the value on “B3” is 3.1 then the grade is 96.18% and the bar is dark green.
if  the value on “B3” is 2.8 then the grade is 100.0% and the bar is dark green.


Next, according to the grade and color obtained, we have to represent this in the bar type graph already mentioned above.

I hope having explained all items involved, and also have given enough examples.

Thank you in advance.
