ZH_Global_Chart_Variable_Lib - library for MetaTrader 4

A global graphical variable (graphical object) is only visible to the programs of one window.

Any data entry is a text entry in the properties of the grapical object. The length of the entry can not exceed 62 symbols.

The functions are provisory divided into four groups.
1. The function returns the numeric value of the global graphical variable.
2. The function returns the string value of the global graphical variable.
3. The function sets a new numeric value to the global graphical variable.
4. The function sets a new string value the global graphical variable.
The functions of working with the graphical arrays.
5. The function changes the value of the specified cell of the graphical array.
6. The function reads the specified cell of the graphical array with the data of the double accuracy.
7. The function returns the number of elements of the specified dimension of the graphical array.
8. The function changes the size of the specified dimension of the graphical array.
Fucntions of working with the graphical files.
9. The function writes a one-dimensional integer array into the graphical file.
10. The function writes a two-dimensional integer array into the graphical file.
11. The function writes a one-dimensional array with the data of double accuracy into the graphical file.
12. The function fills the global graphical two-dimensional array with the values of the double accuracy.
13. The function reads the specified number of elements from a graphical file to the one-dimensional integer array.
14. The function reads all elements from a graphical file to the two-dimensional integer array.
15. The function reads the specified number of elements from a graphical file to the one-dimensional array of the double accuracy data.
16. The function reads all elements from a graphical file to the two-dimensional array with the double accuracy data.
The secondary functions of working with the global graphical variables, arrays and files.
