Hide Date and Price Scales from a chart

 

I'm trying to build a dashboard as need as much real state as possible to fit all the information I need to be able to see. For this reason, I was trying to hide the date and time scales, as I'm not going to trade from the dashboard itself. But when I've used the chart properties and have tried to change the settings, it doesn't work. I have MT4 build 646 installed. I've been using the following:

CHART_SHOW_TRADE_LEVELS and CHART_SHOW_PRICE_SCALE

per the following link: https://docs.mql4.com/en/constants/chartconstants/charts_samples#chart_properties_panel

I'd really appreciate any help so that I can finalize my dashboard. I believe that these properties cannot be changed in the version that I'm using, but would like to confirm it.

Thank you!!

 
It did not work for me either some time ago, and neither many other properties.
 
i think it's not been implemented yet
