Problem with point to point waveform graph

Hi, first sorry for my poor english. but i do this question in the Spanish forum but i dont have response. I have a Vi, in this Vi i get the value of Frequency and Amplitude from an Oscilloscopio. I have a graphic but when i change the frequency from the waveform generator, the graph doesnt save the old point. I need  every time I change the frequency, the point remains in the chart above.Deputy Vi

 

Lo escribo en español, capaz alguien me puede ayudar o me entiende mejor. Tengo el programa mediante el cual con un generador de onda doy señal a un  Oscilloscopio conectado a la pc. Este vino con un programa en Labview al cual agregue un grafico que me grafique a cad frecuencia la amplitud correspondiente. EL problema es que si cambio la frecuencia el punto anterior en el grafico se me borra. Y yo necesito que quede, para ver como cambia la amplitud a lo largo de la frencuencia.

Hi,

      If you change the frequency and amplitude,then defenitely the value at a particular point will changes.Don't understand clearly what you really mean.

      good luck.

Hi mrudaz,

 

you should to use an Waveform Chart instead of the Waveform Graph. This kind of graph have three exhibition modes: Strip Chart (default, use this), Scope chart and Sweep Chart. Only replace the wavefom graph by the waveform chart.
