Describe the bug
I am currently making a test program during my internship. I have come across a bug relating toward the y_axis_precision value. If I put the value to 0 to make it look cleaner I can see the line doesn't cross with the grid. If I put the value on 5 it will work correctly. Although I don't like the 5 decimals.

Expected behavior
With the current code it will work but if you change the y_axis_precision to 0 you can see after some time it isn't reliable.

This doesnt seem to be working, i get the following error.
chart_1 = tkchart.LineChart(master=root

ValueError: 'width' and 'height' arguments must be passed to the constructor of the widget, not the place method
The cget() function was not found, how should I go about getting the relevant parameter values? Also, the x-axis coordinate display function doesn't seem to be available?
没有发现cget()函数，我应该怎样去获取相关的参数值？此外，x轴坐标显示功能似乎也没有？
