If there is data, we through the control display histogram I believe that everyone did,

But if only the histogram, can you read the figure resolution for the data? Each column consists of (coordinates x, y, altitude),

As reference, there is nothing good, below, thank you,

CodePudding user response:

Data is not necessarily completely consistent, and the original data proportion relationship or no problem!
Although this is a simple image processing, but the amount of code or some
First, to be able to identify bar, such as the middle vertical dashed line is not a part of the data, and then get all the columns at the center of the x coordinate and y coordinate
On the basis of the x coordinate draw or calculate the appropriate interval value, then the x coordinates are converted to an integer

Machine vision category, you tell how to understand "the machine", so please define the meaning of the "column", teach a computer how to identify the "column", convolution, filtering or will do, of course, such a simple figure, you with the most basic sampling)

So the question, ask you to ai plate, we can only tell you the direction, can't tell you, after all, this is not our professional,

Is, of course, my personal knowledge, the PIL python libraries have getdata method, it is somebody else's good, as for the effect how, that's hard to say (effect should be ok. After all, the chart is the standard sample cases, rules to learn, or connect to learn or are easier to play)

CodePudding user response:

Study the realization of the chart, is, after all, the existing data, and then draw the figure
There may be related properties

CodePudding user response:

Can regardless of the implementation details, first I want to know to have good implementation approach?
With the right mentality and then to study the implementation details.
Because the picture is the third party software screenshots, I need to parse, and then do some calculation and analysis

CodePudding user response:

My purpose is to find out the rules of red and green histogram, height and density
If is this, have other measure?

According to the x coordinates, or calculate the appropriate interval value, and then put the x coordinate into integer

Well, data is not necessarily consistent with the original, the each relationship, as long as can according to their own definition, and then can do the calculation and analysis on ok
