Hi I have this problem: I need that the BARGAUGE control (in horizontal position) works in this way: the bar position corresponding with the min value is to the right (and of course the position corresponding to the max value is to the left). Any idea? Thank you. Pietro Cremonini |

Subtract your required value from the full scale reading and use the result. e.g. if the max value is 100 and you want to show 20 from the right use 100-20 = 80 to draw the bar graph. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Hi Mixtel90, thank you for your reply but it seems that my problem is not solved Pietro |

Normally you have (according to the manual) GUI BARGAUGE #ref, StartX, StartY, width, height, Fcolour, Bcolour, min, max, c1, ta, c2, tb, c3, ct, c4 where ,c1,ta,c2,tb,c3,tc,t4 are optional I assume you have a simple 2-colour horizontal bar gauge working but with min on the left and max on the right? StartX and StartY set the top left position of the gauge. To get it horizontal the width has to be greater than the height. Fcolour and Bcolour are foreground and background colours. min sets the minimum value and max sets the maximum value. These will be at the LH and RH ends of the bar. #ref is the unique reference number that you've given this control. You change the value on the bar by using something like CtrlVal(#ref) = yourvalue if you have min set to 0 and max set to 100 then CtrlVal(#ref) = 20 will display a value of 20 on the bar (1/5 of the way along) If you use CtrlVal(#ref) = (100-20) then the display will be at the 80 position. (100-0) will put the display at the max end (100-100) will put it at the min end. Of course, the colours may be opposite to what you want but you can specify them. Get an ordinary horizontal bar graph working first, even if the direction is wrong. If you are still having problems then please post a short piece of code that shows us what your problem is.
