Showing score on graph

Hi kglad,

Thanks for your reply.

In the final analysis, I was not able to get the range settings correct with the moving bar and param F.

As an example, if 1.75 is the "zero" point (mean) in a specific range of scores, and the standard deviation (SD) is .80 (like the bar graph above), then I am not sure what to use to set the min/max. If I set it as +-3 SD's (in this example, (min = -0.65 and max = +4.15), then small positive scores like .75 which are below the zero point (1.75)  make the bar go  down, but not as far as it should. I think this is because the "zero" point is 0 and not 1.75 as it should be.

A .75 score in this example is in the -2 SD range, which makes it a  highly negative score. Maybe, my design is defective and can't be used to contextualize and display a normal distribution score. If I had designed it correctly, a .75 should display a bar going far down, not even a little bit down.

So, I redesigned this to use an image of the normal distribution bar graph for a specific data set, and then to try to dynamically show the specific score on the bottom using placement of a blue dot (like the example, above). But how to set this up in script, using paramF, etc. is the same challenge as the bar design that has failed. (And, in placing the blue dot, no movement is needed: just having it show in the correct location along the bottom of the graph, so the score corresponds with the X location on the graph.)

Here is my last paramF script, with the new values added. It does drive the bar down, but only a small amount. Maybe there is some way to reset some value so that it would show a bigger down movement? However, please note that if paramF could be fixed and adapted to the blue dot placement and graph, it would be ScaleX, not ScaleY, since blue dot placement would change on the X axis, not Y.

paramF(-0.65,-1,4.15,1);

var tween1:Tween = new Tween(bar1_mc, "scaleY", Strong.easeOut, 0, m*Dprime1+b, 2, true);  // where bar1_mc is your bar display for DPrime1

function paramF(x1:Number,y1:Number,x2:Number,y2:Number){

    m = (y1-y2)/(x1-x2);

    b = y1-m*x1;

}

My best guess, as mentioned, is that my bar/column design to display this score as part of a normal distribution, is faulty, and a different  approach, like the normal distribution graph and placement of a blue  dot to display the score, if scripted successfully, may be a design that  succeeds.
