I need a very specific chart app and just don't have time to do it myself or even look to see if it is easy. I want it in B4A so I can modify/finish it myself.
It is a point chart used for looking at tolerance changes in machining. And should look something like this:
You need to be able to set the colors and the locations of the bars, as well as how many points to display (really, this is the distance between points). Points get added starting on the left until the chart is full, then start scrolling off the screen to the left.
What happens is this:
User enters the desired measurement (black line), and the upper and lower limits (Red Lines). There is a formula that calculates the yellow lines and they move depending on how close to tolerance the measurements are. As you can see if points fall outside the tolerance they need to be a different color.
You can actually have a tolerance of, Say +X and -0 so the black line and one of the red lines would be on top of each other, so this might be shown as say a dashed red and black line. In reality, this is rare. When a tolerance is say 10 +.02 -0 users will set the graph up as say 10.01+-.01 or 10.005 +.015 -.005.
It also must handle points that are "Off the chart" gracefully. We do NOT scale the chart to fit all points. They should probably be indicated by a different color or perhaps change the size of the point depending on how far off it is. These should be very rare as should anything outside the red lines as anything outside the red is a reject.
I would like to be able to set all colors, and probably I will determine the dot colors although an option to have the graph set them based on whether they are inside or outside the lines might be pretty cool.
Ideally I would Get from the graph the height, then pass back the location of each line, after that I could simply pass each new point and the graph would calculate where it goes.
An option to display a mean line and/or a trend line would also be nice. An option to display the measurement and/or touch the point and have it display the measurement would also be cool.
Should be able to display text above or below each line, Left, Right, Or Centered (All Three?)
The ability to swipe the screen and look back at the history that scrolled off the screen also very cool.
In reality a user will be entering multiple measurements for a part each time he takes it off a machine, each of which will have its own graph, so having multiple instances of the graph might be a lot simpler than storing and reloading all the data for each measurement?
This is an add on to a much larger Windows App. We plan to sell it stand-alone as a "Teaser" for our main program as well as integrate it with our full program. So we will need to be able to store entered data and also transfer it to PC databases. That part I can handle, but I have a lot to do and wouldn't mind giving that part up either if you are interested and the price is right. Cost is very much a consideration, if it is too much I will just have to put it off and do it myself later.
Leave a message if you are interested or have any questions.
Thanks
