hello i am plotting the 2 data data into the intensity plot.its working finein the 2 d data time,frequency,amplitude three columns respectivelyi am simply plotting the data into required format the plot is ok
where as frequency varies from 20 MHz to 120 MHz of 401 points so i
am giving some offset and multiplier values its ok ,then 1000 of
columns of various time data.when i am moving the cursor previously its showing the corresponding frequencies value .
when i do some modification to get the plot with the x axis
available with my data , then the problem occurs. after plotting the
data giving some x axis offset and multiplier vales as shown in the
picture.from the block diagram u can find out how i am getting the
frequencies plot by getting the index . now index varies only from
12..-13 only so i am getting only the two data's.
what i want to do nowhow can i get the x axis values ..so that i can get my required frequency plot1.when i am plotting the data with out putting any multipier andoffset values to the x axis its seems to be ok.then when i am moving the curssor in the intensity plot coresspondingxy vales i am getting, becoz the x values starts from zero to 1200.ok2. my requirement is after putting the offset and multiplier then thex axis values becomes in float and varies between small values. theoffset value is the very first data of time column and i am givingsome 250ms of multiplier values ok3. each plot contains 5 mins of data with the time interval of 250 msok
.
