GetYByValue returns distinct pixels between prices

Hello,

I'm doing an indicator in NinjaTrader 8 that use the function GetYByValue and I don't understand the values than it returns because sometimes increments 1 pixel. With an example better:
I have TickSize of 0.25
If I call this function for some prices, the results (for example) are:
GetYByValue(1700.00) returns 100
GetYByValue(1700.25) returns 120
I say ok, the distance between ticksize's is 20 pixels, but ...
GetYByValue(1700.50) returns 140
GetYByValue(1700.75) returns 160
GetYByValue(1701.00) returns 180
GetYByValue(1701.25) returns 201 ---> Why the distance now is 21???
GetYByValue(1701.50) returns 221 -> Now is 20 pixel of distance again

The problem is the indicator, the properties of Chart, ...?

Thanks

Hello again

The problem is because this function retuns pixels than are numbers without decimals?

I explain what is my problem. I use this function for calculate each price what is its y-position and then drawing a rectangle with the Volume Total on each level price. How each bar sometimes begins 1pixel more than previous, you can see a separation between some bars. I don't like how visually is it.

How can i do this? Maybe with the function GetYByValueWpf?

Thanks.
