The invention discloses a dimension adjustment processing method of a data model of a data visualized anti-cheating system. The method comprises the following steps: step 1), acquiring a data processing result of an anti-cheating system, showing the data processing result to a user through visualization, and displaying a cheating quantity under a preset dimension; step 2), judging whether the cheating quantity in the preset time period is in a preset threshold value, and determining that a certain dimension of the data is attenuated if the cheating quantity is smaller than or greater than thethreshold value; step 3), acquiring the attenuated dimension of the data model and setting data, and judging whether the dimension needs to be adjusted or not according to comparison between externaldata and the setting data; 4) noticing the data model to carry out dimension adjustment according to the actual conditions of the dimension and the external data so as to form a new data model.
