| 2 | ============ |

| 3 | |
|---|
| 4 | key: zoom amplitudes |
|---|
| 5 | |
|---|
| 6 | Changes the amplitudes of the traces in the display. The |
|---|
| 7 | amplitudes of the specified traces are multiplied by <factor>. |
|---|
| 8 | The trace data are not changed, the "zoom" command affects |
|---|
| 9 | the display only. The zoom parameter is not accumulative, that |
|---|
| 10 | means if you specify the command "zoom all 2" twice, then the |
|---|
| 11 | second command doesn't change anything. To reset the amplitudes |
|---|
| 12 | to initial values enter the command "zoom all 1.0". |
|---|
| 13 | |

|---|
| 15 | parameters: |
|---|
| 16 | ----------- |
|---|
| 17 | |
|---|
| 18 | <trc-list> --- parameter type: trace list |
|---|
| 19 | List of traces to be zoomed. If omitted, all traces are zoomed. |
|---|
| 20 | |
|---|
| 21 | <factor> --- parameter type: real |
|---|
| 22 | Factor by which the trace amplitudes are multiplied. |

| 25 | qualifiers |
|---|
| 26 | ---------- |
|---|
| 27 | |
|---|
| 28 | /default |
|---|
| 29 | The given value of <factor> as a zoom factor is used for all |
|---|
| 30 | new created traces as a default value. |
|---|
| 31 | |
|---|
| 32 | /rel |
|---|
| 33 | The specified zoom factor <zoom> is multiplied to the already |
|---|
| 34 | existing zoom factor of each trace, i.e. <zoom> is a relative |
|---|
| 35 | zoom factor. |
|---|
| 36 | |
|---|
| 37 | |
|---|
| 38 | examples: |
|---|
| 39 | |
|---|
| 40 | zoom all 2.0 ! doubles amplitudes of all traces on display |
|---|
| 41 | ! of not yet zoomed |
|---|
| 42 | |
|---|
| 43 | zoom 1-3 1.0 ! resets amplitudes of first three traces |
|---|
| 44 | ! to initial values |
|---|
| 45 | |
|---|
| 46 | zoom/default all 3.0 ! displays amplitudes of all traces on display |
|---|
| 47 | ! three times larger than on initial display. |
|---|
| 48 | ! Also all traces created after this command |
|---|
| 49 | ! will be displayed with this magnified amplitude. |
|---|
| 50 | |
|---|
| 51 | zoom/rel all 2 ! Amplifies all amplitudes by a factor of 2, |
|---|
| 52 | ! no matter what the current zoom factor is |
|---|
